I have to admit I'm a little surprised the M4's effective range is mentioned as 600 meters. Aren't there problems with the 5.56 NATO's ability to wound when being fired from an M4 carbine, due to the shortness of the barrel?
No handguard? Obviously she's going to use it to escape from New York.
That or it's a reference to that photo of some Australian SASR guys in Vietnam, one of whom has a SLR with no handguard and a XM148.

IIRC the "600 meters" number is against area targets, point targets are more around 400-500 as I recall.

More like 300 and 400 if you're lucky and a hell of a shot. At 300 meters 5.56 begins to tumble, which while good for damage seriously fuckss with range and accuracy.

This is complete nonsense, just stop. 5.56 fired out of a 14.5" barrel stays supersonic out to WAY over 500 m. It doesn't start to "tumble" until it hits something.
Now fragmentation (the key advanced wounding mechanism of military 5.56 loads) is a different issue. Reliable fragmentation depends on velocity. Short barrels translate to low muzzle velocity, which translates to the round dropping below its fragmentation threshold sooner after leaving the muzzle. Out of 14.5" barrels, a M193 55gr bullet fragments RELIABLY up to approximately 90 yards (it usually still fragments up to over twice that distance, but you can't depend on it anymore). M855 62gr only fragments reliably up to 65 yards.
Don't misunderstand, the round will still make a hole in you at 500 yards. It just won't cause nearly as much tissue damage and bleeding as a properly fragmented bullet. Marines qualify at 500m on a regular basis with their M16A2 and M16A4s using point targets.
If you need to use a short-barreled AR-15 clone, heavy grain OTM loads (69-75gr) are your best bet, as they're still very effective even at much lower velocities.
